Description

Technical Field

[0001] This utility model relates to the field of combat boot technology, specifically a round-toed, cold-weather combat boot. Background Technology

[0002] Combat boots are designed specifically for military personnel or related units for training and combat needs. In addition to basic durability and abrasion resistance, modern combat boots must offer excellent grip, increase ankle stability, and protect the feet. Besides general combat boots, there are also jungle combat boots, desert combat boots, snow combat boots, paratrooper combat boots, and tank combat boots specifically designed for different combat environments, as well as tank combat boots for tank operators.

[0003] Traditional shoe soles mostly use rubber of a single hardness, which is insufficient for grip in low-temperature icy and snowy environments, and becomes too hard and reduces comfort when entering normal temperature terrain. The protective structure of the round toe is simple, mostly made of a single layer of leather or ordinary plastic, which makes it difficult to balance puncture resistance, abrasion resistance and freedom of toe movement. This can easily lead to toe injuries during kicks or severe wear and tear after long-term use. Therefore, how to design a round-toe cold-weather combat boot has become a problem that we need to solve. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a round-toed cold-proof combat boot, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a round-toed cold-weather combat boot, comprising a sole and a cold-weather boot upper disposed on the sole, wherein the sole is made of variable hardness rubber material, and a shape memory alloy sheet is embedded inside the sole;

[0008] The top of the sole is provided with a round toe on one side of the cold-weather boot upper. The round toe includes a puncture-resistant layer. The outer surface of the puncture-resistant layer is provided with a ceramic particle wear-resistant coating. A silicone cushioning pad is fixedly installed on the inner side of the puncture-resistant layer.

[0009] Preferably, the bottom of the shoe sole has an anti-slip groove.

[0010] Preferably, the outer surface of the cold-proof boot is provided with a heel support and protective pad.

[0011] Preferably, the cold-proof boot upper includes an antibacterial, moisture-absorbing, and heat-generating composite fabric layer, the outer side of which is provided with a high-density down cotton and waterproof membrane composite layer, the outer side of which is provided with a high-strength nylon composite fabric, and the outer side of which is provided with a wear-resistant armor composite fabric.

[0012] Preferably, the outer surface of the wear-resistant armor composite fabric is coated with a silicon carbide ceramic coating.

[0013] Preferably, the outer surface of the ceramic particle wear-resistant coating is provided with anti-slip texture.

[0014] (III) Beneficial Effects

[0015] This utility model provides a round-toed, cold-weather combat boot with the following advantages:

[0016] Firstly, the combination of variable hardness rubber and shape memory alloy plates in the sole increases the hardness of the rubber by shrinking the alloy plates in low-temperature environments, thus enhancing grip on icy and snowy terrain. In normal-temperature environments, the alloy plates expand and restore elasticity, improving walking comfort and achieving all-weather terrain adaptability.

[0017] Secondly, the puncture-resistant layer of the round toe, the wear-resistant ceramic particle coating, and the silicone cushioning work together to resist punctures from sharp objects and external impacts, while reducing toe injuries through silicone cushioning. At the same time, the anti-slip pattern improves the reliability of tactical movements.

[0018] Thirdly, the cold-weather boots utilize an antibacterial, moisture-wicking, and heat-generating composite fabric layer, a high-density down cotton and waterproof membrane composite layer, a high-strength nylon composite fabric, and abrasion-resistant armor composite fabric. Furthermore, the outer surface of the abrasion-resistant armor composite fabric is coated with a silicon carbide ceramic coating. This achieves a synergistic effect: the inner layer keeps the feet dry and warm, the middle layer provides both cold protection and breathability, and the outer layer enhances abrasion resistance and protection. This comprehensively meets the multiple requirements of warmth, breathability, and abrasion resistance in combat environments. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a round-toed cold-weather combat boot, including a sole 1 and a cold-weather boot upper 2 disposed on the sole 1. The bottom of the sole 1 has anti-slip grooves 5, which can quickly dissipate foreign objects on muddy, wet, or icy surfaces. Combined with variable-hardness rubber material, this significantly improves the grip of the sole 1 and reduces the risk of slipping. The outer surface of the cold-weather boot upper 2 is provided with a heel support pad 6, which is made of highly elastic polyurethane material. Its arc-shaped design conforms to the ankle contour, enhancing stability and reducing the probability of ankle sprains.

[0028] Furthermore, the cold-weather boot upper 2 includes an antibacterial, moisture-wicking, and heat-generating composite fabric layer 21, which is made of a blended brushed fabric of milk protein fiber and polyester fiber. The outer surface of the antibacterial, moisture-wicking, and heat-generating composite fabric layer 21 is provided with a high-density down cotton and waterproof membrane composite layer 22. The inner layer of the high-density down cotton and waterproof membrane composite layer 22 is a white goose down filling layer, and the outer layer is directly laminated with an ePTFE waterproof and breathable membrane. The outer surface of the high-density down cotton and waterproof membrane composite layer 22 is provided with a high-strength nylon composite fabric 23, which is a blend of Cordura nylon and aramid fiber, and is impregnated with a water-repellent agent (6% fluorine content). The outer surface of the high-strength nylon composite fabric 23 is provided with an abrasion-resistant armor composite fabric 24, the main body of which is a 1mm thick polyurethane-rubber blend layer (70% polyurethane). The four-layer structure, from the inside out, synergistically provides antibacterial and moisture-wicking properties, cold and waterproof protection, structural support, and outer protection. The antibacterial, moisture-wicking, and heat-generating composite fabric layer 21 keeps feet dry; the high-density down cotton and waterproof membrane composite layer 22 blocks external low temperatures while preventing moisture penetration; the high-strength nylon composite fabric 23 enhances the tear resistance of the boot upper; and the abrasion-resistant armor composite fabric 24 improves overall durability. The outer surface of the abrasion-resistant armor composite fabric 24 is coated with a silicon carbide ceramic coating 7, which enhances the abrasion resistance of the cold-weather boot upper 2 and provides a certain degree of corrosion resistance, making it suitable for long-term use in complex outdoor environments.

[0029] Furthermore, the outer surface of the wear-resistant armor composite fabric 24 is coated with a silicon carbide ceramic coating 7. The silicon carbide ceramic coating 7 can improve the wear resistance of the cold-proof boot surface 2, and at the same time has a certain degree of corrosion resistance, making it suitable for long-term use in complex outdoor environments.

[0030] Furthermore, the sole 1 is made of variable hardness rubber, and a shape memory alloy plate 3 is embedded inside the sole 1. A rounded toe 4 is located on one side of the upper 2 of the cold-weather boot at the top of the sole 1. The rounded toe 4 includes a puncture-resistant layer 41, which is a composite woven layer of Kevlar fiber and ultra-high molecular weight polyethylene. The outer surface of the puncture-resistant layer 41 is coated with a ceramic particle abrasion-resistant coating 42, and a silicone cushioning pad 43 is fixedly installed on the inner side of the puncture-resistant layer 41. The outer side of the ceramic particle abrasion-resistant coating 42 has anti-slip patterns, which increase friction with objects during climbing or kicking, improving the stability of tactical movements.

[0031] The working process of this utility model is as follows: When in a low-temperature environment, the shape memory alloy sheet 3 inside the sole 1 shrinks, causing the variable hardness rubber material to harden. At this time, the anti-slip groove 5 at the bottom of the sole 1 can fit more tightly into slippery terrains such as ice and snow, enhancing grip and preventing slipping. When the temperature rises, the shape memory alloy sheet 3 returns to its original shape, and the variable hardness rubber softens. The anti-slip groove 5 can also better adapt to normal terrain, improving the comfort of walking.

[0032] The three-layer structure of the round toe 4 works together to provide protection: the outer ceramic particle wear-resistant coating 42 can effectively resist wear when in contact with external objects, and its surface anti-slip texture further increases the friction when in contact, reducing slippage; the middle anti-puncture layer 41 can block the intrusion of sharp objects and provide solid protection for the toes; the inner silicone cushioning pad 43 can deform when impacted, absorbing some of the impact force, while its good flexibility provides enough room for the toes to move freely.

[0033] The four-layer structure of the cold-weather boot upper 2 works together to achieve a balance between warmth, breathability, and protection. The inner antibacterial, moisture-wicking, and heat-generating composite fabric layer 21 absorbs moisture from the feet and helps generate some heat, keeping the feet dry and warm. In the middle high-density down cotton and waterproof membrane composite layer 22, the high-density down cotton effectively blocks external cold air, while the waterproof membrane prevents water from entering and also wicks away moisture from inside the boot to prevent stuffiness. The outer high-strength nylon composite fabric 23 provides good structural support for the boot upper and can resist external scratches and other damage. The outermost abrasion-resistant armor composite fabric 24 further enhances the abrasion resistance of the boot upper, and the silicon carbide ceramic coating 7 sprayed on its outer surface makes this abrasion resistance more durable.
